On the calculation of pipeline insulation thickness

Regarding the calculation of pipe thickness for a given allowable heat loss, both the \"Chemical Process Design Manual\" and GBT8175 provide formulas; essentially, they are the same. However, the former specifies a correction factor, meaning that after the thickness is calculated, it must be multiplied by a factor of 1.1 to 1.4, whereas GBT8175 does not include such a correction. Which one is correct?

Has anyone actually calculated the insulation thickness for pipes?

I have been doing all the calculations according to the process manual; I haven’t used GB8175 at all
